What is the favorite food of the Japanese?

Because the Japanese eating habits have become diversified, it is hard to choose only one dish as their favorite food.
According to a survey conducted by a group of general-public restaurants, the most frequently ordered items are hamburgers, curry and rice, and spaghetti.
These three dishes are favorites at home as well.
In the eyes of foreigners, sushi, tempura and sukiyaki may be typical Japanese dishes, but the Japanese do not eat them every day.
